At present, the world's carriers are commonly used on the hydraulic blocking device, MK7 type blocking device, for example, the use of the blocking rope has two specifications, namely, 6x30 flat steel stranded hemp fiber core blocking rope and 6x30 flat steel stranded polyvinyl acetate core blocking rope. Each blocking rope is composed of 6 strands of steel wire rope, each strand of steel wire rope is composed of 12 main steel wire, 12 intermediate scale steel wire and 6 is a triangular arrangement of fine steel wire twisted into. Between each strand of steel wire rope there is a cross wire, each wire rope core is also equipped with oil-impregnated hemp fibers, the core of the rope also indicates that the blocking rope manufacturer's identification band.

Interdiction steel cable needs to directly withstand the impact of the aircraft tail hook and blocking force, but also to have a high fatigue continuous performance, hardness and toughness requirements for the material process of interdiction cable put forward stringent requirements. The principle technology of aircraft blocking is very difficult. One of the unique structure of the blocking cable support system, it is a blocking cable elevated to a specified height of the device, in order to be able to lift the tail hook of the aircraft after the skidding.

Interceptor, used to stop the aircraft at high speed, is the literally "lifeline". With the shore-based aircraft landing can be slow deceleration level flight is very different, the plane landing must be accelerated landing, once the blocking cable tail hook failed to hang the aircraft, must be able to quickly pull up to escape. Therefore, the landing of aircraft on the deck blocking device requirements are extremely high./span>
